Summary by Sourcery

Bug Fixes:

• Fix missing style html attribute support on Card header and InputGroupLabel components

Enhancements:

• Refactor BootstrapInputGroupLabel into a sealed class deriving from DisplayBase and implement BuildRenderTree to include AdditionalAttributes and style attributes
• Include AdditionalAttributes style entries in Card.HeaderStyleString via AddStyleFromAttributes

Reviewer's Guide

This PR fixes the missing style HTML attribute propagation by overriding the render logic in BootstrapInputGroupLabel to emit class, style, required flag and arbitrary attributes, and by extending the Card header style builder to include AdditionalAttributes.
